Description

Technical Field

[0001] This invention relates to a method for qualitative and localization analysis of fingertip pulse, as well as an information acquisition method and analysis system for this method, and particularly to a method and system for qualitative and localization analysis of the acquired fingertip pulse based on the physiological and pathological principles of traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine (TCM) doctors use varying degrees of pressure with their fingers to sense the pulse at the patient's wrist, using this pulse as one of the bases for physiological and pathological analysis. The doctor applies pressure at three levels—superficial, middle, and deep—to the three points (cun, guan, and chi) on the patient's wrist, thus obtaining a multi-dimensional, qualitative, and localized pulse reading. This allows for the examination of the patient's pulse condition and serves as an important basis for physiological and pathological analysis, applicable to teaching, research, and clinical practice.

[0003] Currently, most pulse analysis instruments primarily target wrist pulses, with pulse information derived from the radial artery at the wrist. These instruments are typically fixed wrist pulse analysis devices, attached to the subject's wrist to directly sense the radial artery at the cun-kou (radial artery) point. These devices often employ single-point or matrix pressure sensors. However, variations in the location of the radial artery at the cun-kou point among different subjects, coupled with operator errors in locating the pulse at the sensory components, lead to significant differences in the pulse images obtained by the wrist pulse analysis instrument, affecting the accuracy of the analysis. Furthermore, existing equipment is cumbersome to operate and inconvenient to use, hindering practical applications, especially for remote pulse analysis in the era of big data, thus impeding the widespread application of Traditional Chinese Medicine.

[0004] Currently, there are other pulse analysis instruments based on different principles or types. Their pulse detection and acquisition are also based on the multi-dimensional qualitative features of pulse characteristic maps (such as: wiry pulse, slippery pulse, thready pulse, rapid pulse, etc., each with its own different multi-dimensional information corresponding to pulse characteristic maps). They can often only determine the general information of the subject's physiological and pathological functional state (such as the nature of the disease, i.e., the disease nature), but cannot confirm the location of the subject's physiological and pathological functional state (such as the disease location, i.e., the disease location) from the perspective of multi-dimensional positioning of the three parts and nine pulses. It is difficult to form the full-element information of qualitative + location (disease nature + disease location) required for pulse analysis, and cannot fully achieve the purpose of pulse analysis. Therefore, it also seriously hinders the effective application of pulse analysis instruments.

[0005] Therefore, in order to effectively achieve the complete collection and analysis of the three parts and nine pulses of traditional Chinese medicine pulse diagnosis, and to standardize and popularize the application of relevant pulse analysis instruments, it is necessary to improve the existing pulse analysis instruments. Summary of the Invention

[0006] This invention provides a qualitative and locational analysis method for fingertip pulse. This method is based on the pulse information of the photoelectric effect of the fingertips of at least the index, middle, and ring fingers of the left and / or right hands. The fingertip pulses of the index, middle, and ring fingers correspond to the three parts of the three-part, nine-pulse theory of wrist pulse analysis in traditional Chinese medicine: cun-kou, guan-kou, and chi-kou. The method simultaneously performs qualitative and locational analysis on the fingertip pulse. The qualitative analysis refers to determining the physiological and pathological condition corresponding to the pulse through the multi-dimensional information of the pulse feature map. The locational analysis refers to determining the multi-dimensional location corresponding to the physiological and pathological condition of the pulse, that is, the fingertip pulses of the index, middle, and ring fingers correspond to the cun-kou, guan-kou, and chi-kou locations, respectively, as well as the superficial and deep layers represented by light, medium, and heavy palpation.

[0007] On the other hand, when analyzing the pulse information of a fingertip, the pulse information of that fingertip is the primary information, while the information of one or two adjacent fingers is used as auxiliary information.

[0008] On the other hand, when collecting the pulse information of each fingertip, the pressure value applied to each finger is marked as heavy, medium or light according to the settings.

[0009] On the other hand, the analysis method also includes refinement and optimization based on big data, statistical or artificial intelligence algorithms.

[0010] A method for information acquisition for the qualitative and localization analysis of fingertip pulse characteristics described in any of the above-mentioned methods is also provided. This acquisition method includes a startup step and an acquisition step. In the startup step, it is determined whether a startup condition is met. If the startup condition is met, the acquisition step is executed, whereby the fingertip pulse characteristics of the left hand and / or right hand are specifically acquired. The acquisition step includes a light emission step and a light reception step. In the light emission step, a light source emits light according to a set procedure. In the light reception step, a photodetector receives the light emitted by the light source after attenuation by the fingers, and the reflected light, thus completing the acquisition of qualitative information.

[0011] On the other hand, the fingertip pulse information of the index, middle and ring fingers of the left and / or right hands is collected sequentially, synchronously or randomly in the collection steps. Based on the completion of qualitative information, the location information is collected. When collecting randomly, the collected fingers are marked to indicate which finger it is.

[0012] On the other hand, the fingertip pulse information of some or all fingers of the left and / or right hand is collected sequentially, synchronously or randomly in the collection steps. Based on the completion of qualitative information, the location information is collected. During the collection, the collected fingers are identified to indicate which finger it is.

[0013] On the other hand, the activation condition is that the pressure applied to the finger exceeds a predetermined threshold or the time the finger blocks the light source exceeds a predetermined threshold.

[0014] On the other hand, the collection step also includes acquiring data from big data.

[0015] A system for analyzing fingertip pulse characteristics using a qualitative and localization analysis method is also provided, comprising: an information input module for collecting fingertip pulse information of an object according to a collection method, including information for qualitative analysis and information for localization analysis; an information transmission module for transmitting information between various modules of the system, the transmission including input and output; an information processing module for analyzing the fingertip pulse information collected by the information input module; an information output module for outputting and displaying the analysis results of the information processing module; and a control module for controlling the operation of the information input module, the information transmission module, the information processing module, and the information output module.

[0016] On the other hand, the information input module uses photoplethysmography (PPG) to collect pulse information from the fingertips.

[0017] On the other hand, the information input module is a communication device with a camera component, wherein the camera component is used as a light source, and the light emitted by the light source after being attenuated by the finger is received by the built-in photoelectric receiver of the communication device to obtain the qualitative information of the fingertip pulse. At the same time, the corresponding positioning information is obtained according to the aforementioned information acquisition method, thereby completing the acquisition of positioning and qualitative information, which is then analyzed by the system to give the results.

[0018] On the other hand, the information input module is a dedicated device for collecting fingertip pulse information. The dedicated device has one or more fingertip acquisition components with lenses for qualitative and localization of fingertip pulses in the left and / or right hands of the subject, and the information input module includes a built-in light source and a photoelectric receiver.

[0019] On the other hand, the dedicated device includes three or six fingertip acquisition components, which respectively acquire the fingertip pulse location information of the index, middle, and ring fingers of the left and / or right hands, thereby completing the acquisition of location and qualitative information, which is then analyzed by the system to give the results.

[0020] On the other hand, the dedicated device includes five or ten fingertip acquisition components, which respectively collect the fingertip pulse location information of all fingers of the left hand and / or right hand, thereby completing the acquisition of location and qualitative information, which is then analyzed by the system to give the results.

[0021] On the other hand, the information input module has a built-in pressure sensor. When the pressure sensor senses that the pressure of a finger covering the information input module exceeds a predetermined threshold, the control module activates the light source and photoelectric receiver of the information input module.

[0022] On the other hand, the pressure value of the finger pressing on the information input module sensed by the pressure sensor is marked as heavy, medium or light according to the settings.

[0023] On the other hand, the feature is that the information output module can output and display data to a local smart device or remotely send and display data to a third-party smart device.

[0024] On the other hand, the information transmission module is used to transmit data obtained from other information sources to the information processing module, and can transmit the processing results to other information sources.

[0025] On the other hand, the feature is that the information input module, information processing module, and information output module are respectively connected to big data, and respectively collect big data, process big data, and output information to big data based on big data.

[0026] The significant advancement of this invention lies in the fact that, according to the fingertip pulse analysis method, acquisition method, and corresponding analysis system of this invention, traditional wrist pulse analysis is transformed into fingertip pulse analysis. This not only obtains the qualitative information required for traditional Chinese medicine pulse analysis, but more importantly, it simultaneously obtains the locational information necessary for pulse analysis. Only by combining qualitative and locational information can a truly complete pulse analysis be achieved; neither is dispensable. Clearly, this invention not only enables the complete realization of traditional Chinese medicine pulse analysis in a way different from existing methods, but also meets the urgent needs of the big data era, allowing traditional Chinese medicine pulse analysis to be implemented remotely and conveniently without time and space limitations.

[0027] Using the analysis method and system of the present invention, the acquisition component is directly connected to a specific finger of the person being tested, which can also overcome the following obvious defects:

[0028] 1. When testing personnel or doctors take the pulse at the wrist cunkou point, there are often significant individual differences in their perception and understanding of the pulse under their fingers, which affects the accuracy and consistency of pulse analysis.

[0029] 2. When using wrist pulse analysis instruments, the pulse images obtained by the instruments often vary greatly due to the variations in the location of the cun-kou pulse vessels of different subjects (subjects) and the deviations in the pulse location by the operators of the instruments. This affects the accuracy of the analysis.

[0030] Therefore, this invention can make the results of pulse analysis more objective, visual, accurate, stable, reliable, standardized, and regulated, and can be implemented remotely and conveniently without time and space limitations. Attached Figure Description

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, those skilled in the art should understand that this application is not limited to these specific embodiments. Those skilled in the art can conceive of other ways to implement this application based on the described preferred embodiments, and such other ways also fall within the scope of this application.

[0041] The following reference Figure 1-7 The present invention describes in detail the method for analyzing fingertip pulse, as well as the method and system for collecting and analyzing fingertip pulse.

[0042] Figure 1The image shown is a standard radial artery pulse diagram at the wrist, commonly used in traditional Chinese medicine.

This pulse diagram is drawn using data collected by a pressure sensor and contains multivariate characteristic information, including various parameters such as time, amplitude, ratio, and area.

[0043] Table 1 below categorizes the standard features of pulse waveforms into various parameters such as time, amplitude, ratio, and area, and explains the hemodynamic significance and diagnostic value of each parameter.

[0044] Table 1 Definition and Value of Pulse Pattern Characteristic Parameters

[0045]

[0046]

[0047] Figure 2 These are the pulse waves from the radial artery pressure point and the fingertip volume pulse, collected at the same time from the same hand. It is clear that the waveforms and their diverse characteristic information are essentially identical. Furthermore, from... Figure 2 We can also see that the wave at the fingertip has a slight time delay; the fingertip wave is smoother and more stable. From this perspective, using fingertip pulse information for applications is relatively more stable and reliable.

[0048] The inventor of this application is a PhD in Biomedical Engineering, a renowned traditional Chinese medicine practitioner in Guangdong Province, and a chief physician specializing in integrated traditional Chinese and Western medicine. The research shown above discovered that the wrist pressure wave and fingertip volume pulse wave patterns are essentially consistent. Based on relevant interdisciplinary knowledge, research, and clinical experience, the inventor conceived of using the fingertip volume pulse wave as the data basis for pulse analysis instruments, replacing the currently common wrist pressure wave.

[0049] According to the fingertip pulse analysis method of the present invention, the fingertip pulses of the index, middle, and ring fingers correspond to the pulses of the cun, guan, and chi positions in the three-part, nine-position theory of pulse analysis in traditional Chinese medicine. This correspondence is due to the inventor's extensive clinical practice and research, during which he collected numerous pulse images of the wrist (cun) and fingers. Analysis of these pulse images revealed that the fingertip pulse images of the index, middle, and ring fingers of these individuals were almost identical to and closely related to their cun, guan, and chi pulse images.

[0050] The three-finger fingertip pulse analysis method of the present invention is based on the fingertip pulse information of at least the index, middle and ring fingers of the left and / or right hands. The fingertip pulses of the index, middle and ring fingers correspond to the pulses of the cun, guan and chi positions in the three-part nine-position theory of pulse analysis in traditional Chinese medicine.

[0051] In addition to the methods described above, based on years of research and practice, the inventors of this application believe that the following analysis method will yield more accurate physiological and pathological conclusions: When analyzing the pulse information at the fingertip of a particular finger, the pulse information at the fingertip of that finger is used as the primary qualitative and locative information, while information from one or two adjacent fingers is referenced as supplementary information.

[0052] The qualitative and locational analysis method of the three parts and nine pulses of the fingertip pulse in this invention is as follows.

[0053] Qualitative analysis: The pulse waveform acquired from the fingertip (fingert volume wave) is very similar to the pulse waveform from the wrist (radial artery pressure wave) (see...). Figure 2 Both methods share similarities in waveform formation principles with the hemodynamic mechanisms of the fingertips and radial arteries in the pulse cycle, and their waveform parameters are comparable. Referring to the relatively mature qualitative multivariate waveform parameters of the wrist pulse characteristic diagram in Traditional Chinese Medicine and the qualitative characteristics of the various pulse types they represent (e.g., wiry pulse, slippery pulse, thready pulse, rapid pulse, etc., each with its own distinct pulse characteristic diagram and corresponding multivariate information), we perform matching and algorithm analysis of the fingertip pulse characteristics. This determines the qualitative characteristics of the various pulse types represented by the fingertip pulse waveform (e.g., wiry pulse, slippery pulse, thready pulse, rapid pulse, etc.), thereby inferring the approximate information (pathological information) of the corresponding physiological and pathological functional state of the tested object. This achieves the transformation and transfer from qualitative analysis of the wrist pulse to qualitative analysis of the fingertip pulse, completing the qualitative analysis of the fingertip pulse.

[0054] Locational Analysis: Based on the Three Divisions and Nine Pulse Diagnosis Method of Traditional Chinese Medicine, the locational meaning is that the Cunkou pulse is divided into three divisions: Cun, Guan, and Chi. Each division is further divided into three positions: floating, medium, and deep, with light, medium, and heavy finger pressure respectively, for a total of nine positions.

[0055] Clinically, the significance of the Three Divisions and Nine Pulses Cun-Kou pulse diagnosis method lies in determining the location and nature of the disease. In terms of location: the heart and small intestine are associated with the left Cun; the liver and gallbladder with the left Guan; the kidney and bladder with the left Chi; the lung and large intestine with the right Cun; the spleen and stomach with the right Guan; and the Mingmen and Sanjiao with the right Chi. The principle of differentiating the organs by the Cun-Kou pulse is of great significance in clinically determining the location (pathological location) of the affected organs.

[0056] Figure 3 This invention relates to a diagram showing the correspondence between the fingertip pulse location and the location of internal organs, derived from the cun-kou pulse location. As mentioned earlier, the pulse characteristics of the index, middle, and ring fingers of the left and right hands correspond to the cun, guan, and chi positions of the radial artery in the left and right hands, respectively. Since the cun, guan, and chi positions of the radial artery in the left and right hands respectively represent the physiological and pathological conditions of various internal organs in the patient, the pulse characteristics of the index, middle, and ring fingers of the left and right hands can also represent the physiological and pathological conditions of various internal organs in the patient.

[0057] Figure 4This is a schematic diagram of a fingertip pulse analysis system according to the present invention. The fingertip pulse analysis system includes an information input module 1, an information transmission module 2, an information processing module 3, an information output module 5, and a control module 4. The following describes each module and their interrelationships in detail.

[0058] Information input module 1 collects the fingertip pulse information of the subject. In this application, information input module 1 utilizes photoplethysmography (PPG) to collect pulse information. PPG uses a photoelectric sensor to receive light emitted from a light source after it has been attenuated by the finger. This technology can detect and record changes in blood volume in the tiny blood vessels surrounding the fingertip. Of course, other technologies can be used to replace PPG, as long as they achieve the same effect.

[0059] Information input module 1 should have a light source, a photodetector, and a lens that allows light to pass through. Information input module 1 has a built-in pressure sensor. When the pressure sensor senses pressure from a fingertip covering information input module 1, it notifies control module 4 to activate the light source and photodetector. During data acquisition, control module 4 marks the pressure value of the finger pressed by the object as either "heavy" or "light" according to a set parameter. A "medium" pressure value can also be added between "heavy" and "light," for example, when the pressure sensor determines that the pressure of the finger pressed by the object is moderate, it is marked as "medium." The pressure value standards for marking "heavy," "medium," and "light" pressure values ​​can be appropriately set based on the experience of those skilled in the art.

[0060] Information input module 1 can be a communication device with a camera. The camera of the communication device is used as a light source, and the light after being attenuated by the finger is received by the built-in photoelectric receiver of the communication device, thereby obtaining the fingertip pulse information.

[0061] The information input module 1 can also be a dedicated device for collecting fingertip pulse information. This dedicated device has multiple fingertip acquisition components with lenses, used to collect the fingertip pulses of the subject's left and / or right hands respectively. The information input module 1 has a built-in light source and photodetector. For example, the information input module 1 can be in the form of a finger clip, ensuring that the clip covers the fingertip of the finger whose pulse needs to be collected, so that the fingertip contacts and presses against the lens of the information input module 1. The information input module 1 can also be in the form of a disc, with the fingertip of the finger whose pulse needs to be collected pressing against the lens of the information input module 1. Those skilled in the art can also use other appropriate forms as needed.

[0062] This specialized device may include 3 or 6 fingertip acquisition components, corresponding to the acquisition of fingertip pulse information of the index, middle, and ring fingers of the left and / or right hands, respectively. The specialized device may also include 5 or 10 fingertip acquisition components, respectively acquiring fingertip pulse information of all fingers of the left and / or right hands.

[0063] The information processing module 3 compares the differences between multiple fingertip data and images based on the fingertip pulse information collected by the information input module 1. Based on the similarities or differences in the pulse of different fingers, and according to the relevant theories and algorithms of traditional Chinese medicine physiological and pathological analysis, it provides the pulse qualitative analysis and the three-part and nine-position location information necessary for traditional Chinese medicine physiological and pathological analysis, and then analyzes the physiological and pathological condition of the object.

[0064] The information output module 5 outputs and displays the analysis results from the information processing module 3. This output and display can be done on a local device or by remotely sending and displaying the data on a third-party smart device, such as a remote computer or smartphone. The displayed content can be intuitive graphics, text, audio, video, or resource data.

[0065] Control module 4 controls the operation of information input module 1 and information processing module 3.

[0066] In addition, such as Figure 5 As shown, the information input module 1, information processing module 3, and information output module 5 can be associated with big data, and respectively collect (input) data, process data, and output information to big data based on big data. This makes data collection more comprehensive, analysis results more accurate, and continuously supplements big data with new information, thereby realizing the objectification, visualization, standardization, and normalization of pulse analysis.

[0067] Figure 6 This is a preset pressure level table in the information input module 1 of the fingertip pulse analysis system of the present invention. Data acquisition commands can also be preset in the information input module 1, for example, setting a light press with the left thumb, a firm press with the left index finger, a firm press with the left middle finger, etc.

[0068] In addition, a separate information transmission module 2 can be set up between each of the above modules so that the data can be processed appropriately while transmitting data, such as amplification, filtering, acceleration, encryption, "desensitization", etc.

[0069] Figure 7 The information processing module 3 of the fingertip pulse analysis system of this invention contains multiple pre-set qualitative pulse diagrams and indicators, characteristics, and parameters of the subject's sub-health state. When the analysis results match the relevant pulse characteristics, the analysis conclusion of the subject's TCM pathophysiological condition (such as sub-health state) can be matched and output.

[0070] The working method of the pulse analysis system of the present invention will be described in detail below. See also Figure 8 The working method of the pulse analysis system mainly includes the information acquisition stage (P1), the data analysis stage (P2), and the information output stage (P3).

[0071] The information collection phase (P1) includes the following steps.

[0072] In the first startup step (S1), the control module 4 determines whether the information input module 1 meets the startup conditions. The startup conditions are that the pressure applied to the finger exceeds a predetermined threshold or the duration for which the finger blocks the light source exceeds a predetermined threshold. For example, a pressure sensor can be built into the information input module 1 as a startup condition component. When pressure is sensed from a finger covering the information input module 1, the pressure sensor notifies the control module 4 to proceed to the next step, the second data acquisition step (S2). Alternatively, if the duration of finger blocking the light source exceeds a predetermined threshold (e.g., 2 seconds), the startup conditions are deemed met, and the control module 4 is notified to proceed to the next step, the second data acquisition step (S2).

[0073] In the second acquisition step (S2), the control module 4 activates the light source and photodetector of the information input module 1 to perform the light emission step (S2-1) and the light reception step (S2-2), respectively. In the light emission step (S2-1), the light source built into the information input module 1 emits light. In the light reception step (S2-2), the photodetector built into the information input module 1 receives the light emitted by the light source after attenuation by the fingers. In the acquisition step (S2), it can acquire the fingertip pulse information of the index, middle, and ring fingers of the left and / or right hand, or it can acquire the fingertip pulse information of all or some fingers of the left and / or right hand. Through the sensing of the pressure sensor in the information input module 1, the acquisition of the fingertip pulse information for each finger is divided into two types based on the pressure applied to the information input module 1: light pressure and heavy pressure. It can also include a marked pressure application.

[0074] When a communication device with a camera (such as a mobile phone) or a dedicated device for collecting pulse information from a single finger is selected as the information input module 1 to perform the collection step (S2), the collection of pulse information from each finger is sequential, i.e., one finger after another. However, when a dedicated device for collecting pulse information from multiple fingers is selected to perform the collection step (S2), the collection of pulse information from multiple fingers can be synchronous, i.e., the fingers whose information needs to be collected are simultaneously pressed on the information input module 1 for collection. Furthermore, although the collection step (S2) typically collects pulse information from the fingertips of the index, middle, and ring fingers, or from all five fingers, it can also collect pulse information from any one or two of the index, middle, and ring fingers. In addition, the collection step (S2) also includes acquiring data from large datasets. Of course, the collection can be sequential, synchronous, or random, as described above. Regardless of whether the information is collected synchronously, sequentially, or randomly from the fingers, the collected fingers are identified to indicate which finger it is.

[0075] The following describes the data analysis phase (P2). After the data acquired in the information acquisition phase (P1) is transmitted to the information processing module 3, the information processing module 3 performs data analysis under the control of the control module 4. In the data analysis phase (P2), the information processing module 3 analyzes the pulse information of the fingertips acquired in the information acquisition phase (P1), and provides qualitative and locational information for TCM physiological and pathological analysis based on relevant algorithms. At the same time, it converts the qualitative and locational information required by TCM into object-recognizable information, including graphics, text, audio, video and / or resource data, which is called the analysis step (S3). In this step, after receiving the acquired location and qualitative pulse signals, the information processing module 3 performs time-domain and frequency-domain analysis calculations on the pulse signals, and compares and analyzes the pulse signal feature information with the basic information source data based on the basic information source feature information or pulse result information pre-stored in the information input module 1. The main methods for analyzing pulse patterns include: multi-factor image interpretation, mathematical modeling, time-domain analysis, rate analysis, frequency-domain analysis, computer-aided intelligent analysis, and autoregressive-moving average model, etc.

[0076] Information input module 1 collects the fingertip pulse information of all or part of the fingers of the left and / or right hand. When information processing module 3 analyzes the fingertip pulse information of the index finger of the left and / or right hand, it uses the fingertip pulse information of the index finger as the primary information, while referring to the fingertip pulse information of the thumb and middle finger of the left and / or right hand as auxiliary information; when analyzing the fingertip pulse information of the middle finger of the left and / or right hand, it uses the fingertip pulse information of the middle finger as the primary information, while referring to the fingertip pulse information of the index and ring fingers of the left and / or right hand as auxiliary information; when analyzing the fingertip pulse information of the ring finger of the left and / or right hand, it uses the fingertip pulse information of the ring finger as the primary information, while referring to the fingertip pulse information of the middle and little fingers of the left and / or right hand as auxiliary information. In other words, even if the fingertip pulse information of all fingers of the left and / or right hand is collected, the main focus of the analysis is on the fingertip pulse information of the index, middle, and ring fingers. The data of the thumb and little finger can be used as auxiliary information for analyzing the fingertip pulse of the index and ring fingers. That is, when detecting the information of the five fingers, since the main focus of the analysis is still on the middle three fingers, it can still correspond to the "cun, guan, chi three parts" positioning analysis information in the fingertip pulse three parts nine pulse analysis method of this invention.

[0077] The fingertips press on the information input module 1 with different degrees of light, medium and heavy pressure (i.e., three levels of pressure: floating, medium and deep) to obtain the fingertip pulse. The fingertip pulse is "light, medium and heavy", thereby obtaining the corresponding "internal and external" related TCM internal and external level positioning information.

[0078] By comparing and analyzing the differences in data between multiple fingertips, and based on the similarities or differences in the veins of different fingers, relevant algorithms are used to analyze and provide specific pulse identification and three-part nine-position location information required for traditional Chinese medicine analysis, thereby providing a complete analysis of the physiological and pathological conditions of the subjects.

[0079] Based on the above methodological analysis, the obtained fingertip pulse information contains dual attributes of qualitative (pathological) and local (pathological location).

[0080] This method of qualitative and locational analysis of fingertip pulse is the three-part and nine-point qualitative and locational analysis method of fingertip pulse proposed by the inventor of this application.

[0081] In addition, the analysis method also includes the improvement and optimization of statistical or artificial intelligence algorithms based on big data.

[0082] The following describes the information output stage (P3). After completing data analysis, the information processing module 3 transmits the analysis results to the information output module 5. Under the control of the control module 4, the information output module 5 executes the information output step (S4). In this step, the information output module 5 visually displays the information to the end user in various forms such as graphics, text, audio, video, and / or resource data. The terminal can be a smart device such as a computer or smartphone. The end user can visually obtain (hear, see) the results of the pulse detection through the screen of a computer or smartphone and understand the physical condition and constitution detected by the pulse. Health advice can even be given, such as suggesting more exercise and drinking more water. Furthermore, information output can also include outputting information to big data, thereby continuously supplementing the big data with new data information, gradually enriching and improving the big data database.

[0083] Industrial applicability
